Dynamic Commenting for 3D Design Drawings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawing files, both 2D and 3D, are static, limiting dynamic feedback and collaboration, as comments are often out of sync and difficult to coordinate across multiple sources, especially when dealing with deep and nested user data.
Innovation Solution
A dynamic commenting system that allows users to attach comments to specific entities within drawing files, with a comment field displaying a leading line to the relevant part, enabling other users to add, respond, and append content, while maintaining the view angle and visibility states associated with the comment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If comments are added to static drawing files, then feedback can be provided, but comments become out of sync with design updates and require manual coordination
Solution Approach 1:
The patent transforms static comments into dynamic, living comments that automatically update when the design changes. Comments are attached to specific design elements and automatically reposition or update their content when those elements move or change in the drawing file, eliminating the need for manual coordination and keeping comments synchronized with design updates.
Solution Approach 2:
The system implements automatic feedback mechanisms where the commenting system monitors design file changes and automatically updates comment positions and content accordingly. This closed-loop feedback ensures comments remain synchronized with the latest design state without requiring manual intervention.
2Measurement precision
If comments are attached to specific entities in nested drawing structures, then precise feedback is enabled, but system complexity increases to manage deep nesting levels
Solution Approach 1:
The patent leverages the existing nested structure of drawing files (assemblies containing parts, parts containing features) by attaching comments to specific elements at any nesting level. The system recursively traverses these nested structures to enable precise comment attachment while managing complexity through the inherent hierarchical organization already present in CAD files.
Solution Approach 2:
The commenting system is segmented into independent modules that can attach, manage, and update comments at different nesting levels independently. This modular approach allows precise feedback on specific entities while managing system complexity through distributed, independent comment management at each hierarchical level.
3Adaptability or versatility
If multiple users collaborate on drawing files, then feedback coordination is needed, but space for comments is limited and reconciliation becomes difficult
Solution Approach 1:
The patent moves comments from a two-dimensional space constraint on the drawing to a multi-dimensional solution including pop-up panels, toolbars, and cloud-based storage. Comments can be displayed in multiple locations and formats, expanding the effective comment space beyond the limited drawing area while maintaining association with specific design elements.
Solution Approach 2:
The commenting system provides universal access to comments through multiple interfaces (on-drawing markers, pop-up panels, cloud access). Multiple users can simultaneously view and add comments without spatial conflicts, as the system manages comment data centrally while allowing concurrent access from different locations and devices.

AI summary
A method, system, and computer program product provide the ability to dynamically collaborate on a design drawing. The design drawing consisting of three-dimensional (3D) data is acquired and displayed in a viewing area. An entity of the design drawing is graphically selected. A text comment is entered. The text comment and an association between the text comment and the selected entity are added to a design drawing file for the design drawing.
